' This invention relates to liquid fuel burners, and ers utilizing in addition to the fuel, a liquid, such as water, which, when vaporized, breaks up the particles of fuel for obtaining maximum combustion- Objects of this invention are to provide a fuel burner which is simple in construction, easy to operate, and does not require the complicated and expensive machines heretofore required in many burners of this type; to provide a burner uniquely constructed and which is adapted to the use of crude oil without the formation of obstructing carbon deposits, thereby to obtain approximately perfect combustion and high heating efliciency; and to provide a liquid fuel burner having the new and improved features of construction hereinafter more particularly described. I 1

. Species of which this invention is a genus are shown. on the accompanying drawings,"

in which:

Fig. 1 is a to plan view of a burner construction embo ymg the invention, with the frusto-conically shaped perforatedhood and casin removed; Fig. 2 is a vertical, sectiona elevation on the line 22 of Fig. 1.

The illustrated embodiment of the invention comprises a horizontally disposed metallic plate 1 provided with an upstanding peripheral flange 2, a relatively small flange 3 spaced inwardly from the flange 2,.and a.

' central hollow boss 4. Formed on the plate 1 between the flanges 2 and 3 are a series of openings 5 which enable air to be sup lied.

to the burner, and on the inside of the ange 3 is formed a basin or trough to which liq- .uid fuel, such as crude oil, may be supplied from a pipe line 6 havin branches termimating in hook shaped en 7 engaging over the e ge of-the flange 3. The end 7 of the pi e line may be unhooked from the flange 3 by lifting upwardly and outwardly and thereafter may be drawn downwardly through the adjacent opening 5.

Formed on the generator plate 1 between the boss 4 and. flange 3 are a plurality of closely spaced. upstanding elongate pins or ;columns 8 which may be integrall formed with the plate l; The upper on s of the pins 8 may ,be upset to provide radial the urner are heated to a relatively. high temperature and assist inthe vaporlzation particularly to that class of burnss 9 and the pinsSin the operation of of the water and fuel supplied to the burner. Also formed on the generator plate 1 and in close juxtaposition to the boss 4 is a series of integral elongate pins 10 which are shorter than the pins 8, the shorter pins being approximately one-half .the height of the pins 8. I

Attach ed in an suitable manner to the pms 10 1s a splas plate 11 having an'upstanding peripheral flange 12 and provided with a plurality of radially extending spouts 13. Water is supplied to the splash plate 11 in any convenient manner, or as illustrated, from a conduit 14 which leads from any suitable source of supply and passes upwardly through the. hollow boss 4, through the splash plate 11 and terminates in a downwardly extending end portion. Water dropping on the splash plate 11 flows therefrom through the spouts 13 into receptacles 15 in the form of a trapezium. The receptacles 15 are supported in any suitable manner between pins 8 and the pins 10 and serve as catch basins for the water overflowing the splash plate 11. While the catch basins may -be used, it has been found "that the blurner. functions satisfactorily without t em.

Supported on the generator plate 1 and positioned on the inside of the flange 2 is 1 an outer casing 16 of substantial height and which maybe suitably secured to the flange 2 to provide a rigid construction. Formed. on the inside of the casing 16 are helical vanes 17 which imparts spiral or circulatory movement to the air admitted to the inside of the casing through the openings 5 so that more eflicient combustion will take place. It is to be noted that the upper or top end of the casin 16 is provided with 'a wall 18 which is is constricted and the spurt of flame therethrough creates a suction to draw in air through the openin s 5, thus lessening the necessity of a fan or lower for this purpose. Supported inside of the casing 16 and restin on the generator plate l'is a frustoconica ly shaped hood 20 having numerous closely spaced apertures 21. The hood 20 is somewhat shorter than the casing 16 and completely encloses the pins 8.

In order to drain the oil or water whenever it is'desired from the generator late 1, a'duct 22'is connected to the plate 1 a jacent formed with an opening 19 so that. the passage of heated gases from the burner the boss 4 and a valve 23 operable by means of a stem handle 24 is attached to the duct 22.

For supporting the generator plate 1 a hollow base 25 is provided, and air for the burner is passed through this base, also the pipes 6 and 14 may extend through it. It

is to be noted that the bottom 26 of the base 25 is inclined downwardly toward a drain 27 so that any water or oil from the drain duct22 may be cleaned from the base. It is also to be noted that should the generator plate 1 become flooded it may overflow the flanges 3 and 4 and pass through the apertures into the base 25 and thence to drain pipe 27.

It has been found desirable to mix a small amount of volatile liquid, such as wood alcohol with the water for aiding in the thorough and eflicient combustion of the fuel. Instarting, therefore, a small amount of gasoline or alcohol may be supplied to the generator plate 1 in any suitable manner as through the conduit 14 and on the generator plate the liquid will s read itself as a .film

and this may be ignite in any suitable way, as by means of an electric ignitor of a type well known in the art. When a generator plate 1 is heated to a suitable degree the uel, such as oil, ma be introduced through the pipe 6 to the p ate, and thereupon the water may be also introduced through the conduit 14 to the splash plate 11.

' It is to be understood that the water is merely dropped upon the splash plate and in passing through thereceptacles' 15 becomes vaporized, .or it may drop to the generator plates where it will be vaporized, and upon vaporization diffuses or breaks up the oil particles so that maximum combustion may take place. Althou h an artificial draught may be necessary t or the air drawn through the, openings 5, it has been found that -the suction created by the outward passage of the gases from the casing 16 draws in a suflicient amount of air for the purpose. It is also to be understood that the elongate pins 8 and 10 serve to radiate and intensify the heat in the region of the splash plate 11 and the generator plate 1 and this aids in the vaporization of the water and the co-mingling of the water, vapor and steam.

An outstanding feature of the invention resides in the construction of the fuel supply line 6 which is provided with a hooked end portion. By means of the hooked end portion the line may be conveniently supported on the flange 3 without emplo ing additional attaching means. It wil be noted that the line 6 may be quickly disengaged from the flange 3 whenever it is desired, without disturbing or molesting any other portion of the burner, and this is particularly advantageous should the supply .line become clogged with carbon or any other tion as hereinbefore described, obtains practi'cally perfect combustion and eliminates almost entirely the smoke which has usually been found quite objectionable with burners of this character. It will be observed that thecompactness of the parts, simplicity of construction and operation, and consequent ly low cost contribute materially to the production of a most efficient and useful burner.

While I have shown and described a construction which is the best form known to me at the present time, it is to be understood 1 that numerous chan es to suitthe difi'ere'nt shapes and sizes of Furnace fire boxes in details of construction and arrangement may be elfected without departing from the spirit of the invention, especially as defined in the appended claims. What I claim is:
